Beit known that we, lvnn JOHNSON and AN- DREW FYRBERG, of Worcester, in the county of Voreester and State of Massachusetts, have invented certain new and useful Improvements in Fire-A'rms;and wedo hereby declare thatthe following'is a full, clear, and exact description of the same, reference being had to the accom panying drawings, forming a part of this speciro fieation, and in which Figures 1, 2, and 3 represent, respectively,

a top or plan view, a side view, and a bottom or under side view of so much of what is known as a concealed-hammer gun as is necessary to illustrate our improvements thereon. Figs. 4 and 5 represent upon an enlarged scale vertical longitudinal sections showing" parts of the gun in elevation and the various operating parts thereof in different positions, as hereinafter more fully described. All the following figii res are shown upon the same enlarged scale. Figs. 6 to 16, inclusive, are detail views in perspective of the various parts which constitute the firing mechanism of the gun. Figs. 17 and 18 represent an under side and top view, respectively, of our improved front stock locking device, hereinafter described. Fig. 19 represent a central vertical longitudinal section through said front stock- 0 locking device, taken on line a a, Fig. 18, also showing a part of the front stock, barrel, and forehand, with the various parts in position preparatory to unlocking the front stock from the barrel. Fig. 20 is a similar section of 5 the aforesaid parts to that shown in Fig-19, with the various parts in position after unlocking the front stock preparatory to re moving said front stock from the arm. Figs.

21 and 22 represent cross-sections of our improved front stock'locking. device, taken on lines b b and b b, respectively, looking in the direction of arrow 0, Fig. 17 and Fig.23 represents an end view of said locking device,looking in the direction of arrow 0.

Our invention relates to what are commonly known as concealedhammer guns, and comprises improvements in the mechanism for raising the hammer, for locking the trigger when the hammer is thus raised or at full-cock,

ing the barrel ,toand' he frame, and for lockfront stock to and from from the forehand of t ing and unlocking the 350,683., dated October 12,1886.

Serial No. 207,305. No model.)

the barrel, all as hereinafter more fully set forth.

To enable others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe it more in detail.

In the drawings, the part marked A represents the frame of the fire-arm, which is made of the proper shape to receive the various parts constituting the firing and barrel-locking mechanism of said arm. To the rear end of said frame may be secured the usual back stock, and toits underside the tr gger-guardB. 55

C is the receiver, and D the forehand of the frame A.

The part marked E is the barrel having the usual notched holding flanges or en rs E E upon the under side thereof, by means of which 0 and the usual slide-bolt F said barrel is fastened to the frame.

Our improvement in said locking device consists only in the manner of operating the sliding bolt to perform said operation, said bolt being used in other fire-arms for the same purpose, but operated in a different manner from that which we have adopted.

G is the hammer; H, the trigger; I, the trig ger-locking lever; J, a vertical plate fitted to slide forward and back; and K, the top lever for operating said plate, as and for the purpose hereinafter described.

The part marked L is the front stock, in which is fitted our improved locking device, 8 also hereinafter described.

The hammer G is fitted to turn upon the pivot-bolt d, secured at'each end, as usual, in frame A. In this instance it is arranged at the right of the plate J, between thelatter and 9c the frame; but said posit-ion may be reversed, if desired, in making the fire-arm. Upon the inner side of said' hammer is formed or socured a stud, e, at right angles thereto, which passes through a slot, 1', in the plate J, and by means of which the hammer is raised to cock the same by the back movement of the plate against said stud, as hereinafter more fully explained. The plate J is also provided with a slot, f, to admit of the same moving back and. forth on the pivot d, and with two arms, y 71.

extending forward, as shown in Figs. 4 and 5, each arm being provided with a stud or pro-.

ection, g h, respectively, for the following usual way, Upon the purpose: The stud g is fittedin an opening, 9*, (see Figs. 4, 5, and 6,) in the head of the top lever or snap, K, a little to one side of its pivot i, and at the proper point to cause the plate J to be moved back by swinging said lever K out from the arm, as indicated by the arrows in Figs. 4 and 5 and dotted lines, Fig. 1. The stud h fits into an opening, 71 in the rear end'of the barrel-locking bolt F. There fore, when the top lever is swung out and the plate J moved back, as above described, said bolt is drawn back with the same, thus disengaging it from the flanges E E on the barrel, and in consequence releasing said barrel, so that it may be removed from the arm in the pressure against the outer end of the top lever being removed the plate J and parts connected therewith are sprung back into their original normal posi tions by means of a suitable spring, J, having a bearing at one end in a notch or recess, j, in frame A, and the opposite end against the rear end of the plate. Said rear end is provided with an arm,]c, projecting back therefrom, which is adapted to come against a stud or projection, l, on the lower end of the trigger-locking lever I,'when the plate is forced back, as hereinbefore specified, therebyswinging said lever on its pivotm' from the position shown by dotted lines, Fig.- 4, and full lines, Fig. 5, to that shown by full lines in Fig. 4, the latter being in the position which it occupies when the trigger is locked. Itis held in each adjusted position, either forward or back, by means of a spring, a, secured at one end to frame A, and whose other end bears upon the lower end of a beveled or curved part, 0, formed upon or secured to said lever in such a manner that when the lever is swung forward cr back the bearing-point against the spring a will come at one side of the vertical center of pivot m, as shown by dotted lines in Figs. 4 and 5. The lever is thus held with snflicient force to preventits moving out of position'accidenlally, while at the same time it may be readily swung on its pivot to unlock the trigger by placing the thumb upon the upper milled or roughened end, in, and drawing back'upon the same, the frame being slotted out to allow said part to extend up through alittleaboveits surface and admitof said oper ation. p, and is held in its lbrward or normal position by the spring (1, secured at one end in frame A, and hearing at its other end against the back of the trigger below its pivot in the usual way. Said trigger is provided upon its front side with a projection, 1', adapted to catch in a notch, r, formed in the under edge of the hammer when the latter is raised, and with an arm, 8, projecting back and up from its back edge, which is adapted to hear at its outer end against the bottom of the lock-1ever I, when by the plate J into the position shown by full lines in Fig. 4. Therefore it is obvious that when the top lever is swung out and the hammer raised, as

' up into same for any The trigger II is hinged upon a pivot, I

previously specified, the shoulder or notch r,

scribed, the trigger H is looked between the bottom of said lever and thenotch in the hammer, thus holding said hammer also in a locked position until released by pulling back the fingcr H of the trigger, said latter operation causing the projection r on the trigger to be drawn out of the notch r in the hammer, and consequently allowing the latter to be sprung down against the usual firing-pin, t, by the mainspring a, which is made'and adapted to perform said operation as in other fire-arms.

Referring to Figs. 4 and the several parts hereinbefore described in firing the arm may be briefly summed up as follows: The top lever is first swung around, (toward the right in this instance, assumingthat the gun is held in position for firing,) which operation, causing the plate J to be forced back, draws the barrel-locking bolt with it, raises the hammer, and also pushes back the lower end of the trigger-locking lever, thus unlocking the barrel and locking the hammer in its full-cocked position. The barrel is now dropped. down or tridge inserted therein, when it is then swung up and locked in .its normal position, the, locking-bolt and bcaring-p0ints on the barrel being, it will be understood, so formed in practice as to admit of the aforesaid operation, but requirt'iig the bolt to be pulled back to unlock the barrel, as hereinbefore described. The gun halving been loaded and the barrel sprung position, as aforesaid, by'now pulling back the upper end of the trigger-lockingle- -ver, as previously described, the arm may be fired in the usual well-known way.

If it is desired at any time to loaded cartridge for another, or remove the other cause, it is simply necessary to push out and held against the lever with the thumb, while atthe same time drawing the trigger with the other hand in a similar manner to performing the same operation with a gun having its hammer upon the exterior thereof.

Our improved device for locking stock in position is constructed and arranged as follows: A plate, 2;, having a head, a, is fitted in the upper part of the wooden portion '0 of the stock, said plate being arranged to come against the under side of the barrel E, while its head 22 is fitted against the forward end of the forehand D, as best shown in Figs. 2, l9, and 20, audits outer contour made to conform with that the stock, being a continuation thereof when the parts are fitted together. Upon the nuder side of the plate 0 is arranged a looking-bolt, w, which is fitted to slide longitudinally thereon in any convenient manner. It is arranged between the head 2: anda flange, w, projecting downward from said plate 11,

the from the projection r, al-' 5, the operation of replace one of the wooden part '0" of and is in this instance held in position upon the plate by a screw, 10*, fastened in said plate, which passes through a slot, 1r, in the bolt, the latter admitting of said bolt moving longitudinally, asabove described. A forward tension isproduced upon thebolt a, which keeps its forward end against the projection w by means ofa spiral spring '10, fitted over a short spindle, 10 extending forward from the bolt through an opening in said projection said spring being arranged between a pin or projection on the outer end of the spindle and the frontside ot' the projection on the plate a. Said plate 2: and bolt in each have a vertical slot formed therein on a line with each other to admit of.the notched projection :0 on the under side of the barrel to be passed through, the aforesaid notch or slot being adapted to receive the bolt when the parts are titted together, and said bolt is allowed to be drawn forward by its spring it, after having been re leased from its sprungbaek position, as hereinafter described.

To the forward end of the bolt 10 is fastened a spring, 9 which extends back a sufficient distance to overlap the forward end of the forehand D. Said spring is made to bear upward, and its outer end shaped in the form of a hook, for the purpose of catching and holding in a notch, y, formed in the under side of the forehand near its forward end, as shown in Fig. 20. \Vhen in its normal position,the spring is diS- engaged from the notch in the forehand, as shown in Figs. 2 and 3, being held down out of said notch by means of hingedlever z. (See Figs. 21 and 22.) Said lever is arranged in a recess formed in the head c at the inner end of the plate a. It is fitted to turn on a pivot, s, and is provided with a shoulder or projection, .2", upon which the spring may restto hold it out of its notch, as above described. The spring isallowed to engage with the notch by swinging the lever z from the position shown by full lines to that shown bydotted lines, Fi 22, said operation causing the shoulder 2" to be moved to one side of said spring, and thus allowing the latter to spring up into the notch. The lever is swung to one side, as aforesaid, by pushing upon its outer roughened or milled end, 2", which projects up through a slot, z, a little outside of the surface of the head 2), as shown in Figs. 21 and 22. A constant pressure is imparted to the lever toward the spring y, so that it will assume its position under said spring when the latter is raised above the holding-notch 2", by means of a spring, interposed between said lever and the head a, as is also shown in the, above figures. A suitable slot is formed in said head for the spring 3 to work in, and it is otherwise recessed or cut out, as well as the stock to receive the various parts of our locking device, hereinbefore described. The plate 2* is in this instance secured to said stock by means of the screws zfz.

Assuming that the stock is locked upon the gun with the hooked end of the spring '31 resting upon the outer surface of the forehand, disengaged from its notch 1 as shown in Figs. 2 and 3, the operation of first unlocking said stock, then removing it, and replacing it in the aforesaid assumed position is as follows: The top lever, K, is first swung out to unlock the barrel, as hereinbefore described. Said barrel is then swung or dropped down from the frame so that the parts will occupy the relative positions shown in Fig. 19, which, as will be observed, causes the notch y to be moved over the hooked end of the spring y.

The lever 2 now being swung from the position shown in Fig. 17, and full lines, Fig. 22, in the direction shown by the arrows into the position indicated by dotted lines in said Fig. 22, the spring 3 being released is forced up, so that its hooked end engages withthe notch y in the forehand, as shown by dotted lines, Fig. 19. The lock-bolt 10 being thus connected with the frame of the gun, when the barrel is unlocked and swung down as aforesaid, it is obvious that by now swinging up and locking the barrel, as shown in Fig. 20, the bolt is drawn back and disengaged from the holdingnoteh in the flange 0c of said barrel, when the stock may then be easily removed therefrom.

In placing the stock back upon the gun it is simply necessary to place the head thereof against the front end of the -forehand, and.

then swing its forward end up against the barrel, a slight pressure only causing the bolt in to be forced back sutiieientl y by the curved corner x on the flange w. to allow the same to spring forward into the holding-notch of said flange, as shown in Fig. 19, the operation being facilitated by curving the bolt at the back end of its slot, as indicated at x in said Figs. 19 and 20.
